Touchpad incorrectly detected as PS/2 mouse in a Samsung RF711 on Ubuntu 11.04

[Michel Schweegmann]

I just installed Ubuntu and Kubuntu 11.04 (x64) and all works great. Only the touchpad is not correctly detected 'cause it works as a regular mouse, but scrolling and multi-touch functions don't work.

"System Settings" in KDE says that there's no synaptics driver installed or correctly arranged. It seems that the system detects the touchpad as a PS/2 mouse from Logitech.

My Notebook: Samsung RF711-S07.

Michel: I think your report is probably a duplicate of bug 681904. Can you test the build I posted there and see if it fixes your touchpad detection?

@sforshee thanks for your answer.
If i install the kernel 3.0 from your URL the system does not start and freezed.
I must choose "Previous linux versions" in GRUB and select "2.6.38" (the Ubuntu-standard kernel)
to start Kubuntu correctly.

[Seth Forshee (sforshee)]

Michel: Would you mind trying the 2.6.38 kernel posted there as well to see if it hangs? I'd also suggest modifying your /etc/default/grub, changing the line that reads:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

  GRUB_CMDLINE_LINUX_DEFAULT=""

and then running 'sudo update-grub'. This will cause messages to be printed to the screen during boot, which could help with determining the cause of your hang.

Thanks!

[Michel Schweegmann (michel-schweegmann)]

I uninstalled the Kernel 3.0 and installed the 2.6.38-11 from your source.
Now all works great and under "system settings" in KDE i can configure it.
Scrolling works, too.

But: Should i ignore all further kernel updates which comes over the update manager
to be sure that the touchpad will be work or should i install them?

Thank you very much!!

[Seth Forshee (sforshee)]

You can either keep that kernel installed or use the dkms package on the other bug, which will get automatically rebuilt when you install new kernels. We probably won't have a fix in the official kernels for a little while yet.
